You can delete a user group.
Deleting a group will also delete its group space. Group membership information of the accounts will be deleted. Accounts will remain intact, however.
Deleting a group will delete its group space and all the files and folders
contained within. Deleted files and folders cannot be recovered. Group members
also lose roles assigned to the group at the next login.
On the “Manage/View” menu, click “Manage Group”.
Select the checkbox(es) of the group(s) (e.g. group01) and click “Delete”.
